1 INTRODUCTION

1.1 GENERAL

The Mag One magnetic central heating lter is the ideal solution
to costly and unnecessary system breakdowns caused by both
magnetic and non-ferrous particulate in uid based systems.

Thanks to its innovative triple action magnetic ltration system,
it identies and retains all types of magnetite and non-ferrous
debris.

The Mag One magnetic central heating lter can be used on
all types of central heating systems in any orientation and it is

recommended, for maximum effect, that it be installed on the
return leg of the circuit, between the last radiator and the boiler/

heat pump.
The isolating at face ball valves, provided with the magnetic lter,

make maintenance and installation quick and simple.
As well as being tted in conjunction with the installation of a new

system, the Mag One magnetic lter is well suited to being retro­tted to an existing system where the boiler/heat pump is being

replaced – protecting new components and increasing the life

span and effectiveness of existing ones.

1.2 HOW A MAGNETIC FILTER
WORKS

Through a combination of innovative product design and a

clever use of the laws of physics, water is guided through the
components of the Mag One to achieve maximum ltration with
each pass of the circuit.

Water enters the lter through our ingenious diverter block and
then passes into the magnetic lter 500 ml capacity pressure drop
chamber.

Here, particulate is forced through the non-ferrous lter and down
towards the magnet. Through a process of natural convection,
water then circulates back to the top of the lter and back into the
system leaving all magnetite and particulate debris captive at the
base of the lter’s magnetic core.

All system contaminants are then easily removed during servicing
by isolating the Mag One from the system and removing the

magnet from the screw cap at the top of the pot then opening the

drain valve, removing the majority of contaminants within the pot
in seconds.

1.3 SAFEKEEPING OF THE
